Thisinvention relates to an improvement in 1 the manner of cutting apart the edges of a tucked paper tube to form a paper bag having longitudinal inward bellows folds and a square bottom.

Figure 1 is a view of a length of tucked paper tube, and Fig. 2 is a cross section of the same. Fig. 3 is a view of the tube of Figs. 1 and 2 after itslower corners have been cut away on the diagonal broken lines of Fig. 1. Fig. 4 is a view of the tube of Fig. 3after its lower end has been opened out and folded down so as to present the flaps shown therein. Fig. 5 is a view of the blank of Fig. 4, with its two side flaps folded back into place and with paste applied to the presented surfaces of the other two flaps. Fig. 6 is a view of the blank of Fig. 5, with one of the latter flaps folded and pasted down in place; and Fig. 7 isa View of the same with both those flaps thus folded and thus pasted and the bag thus completed. Fig. 8 is a perspective View of the bag of Fig. 7, opened out for use, but with its bottom turned upward in order to show the construction thereof.

To make this bag, a length of tucked paper Serial No.194.962. (No model.)

tube, like thatof Fig. 1, is taken and its lower corners are cut off on lines which are inclined from the longitudinal edges of the tube toward the center thereof. Then the lower end of the tube is opened out and the upper wall thereof is folded back on the transverse dotted line'of Fig. 3. That operation causes the formation of the blank of Fig. 4, having the four flaps A, B, G, and D. Then the flaps A and B are folded down on lines coincident with the respective sides of the body of the blank, and after paste has been applied to the presented surfaces of the flaps O and D, as shown in Fig. 5, those flaps are successively folded down on the dotted lines 3 1 and z z,

respectively, and the bag of Fig.7 is thus FELIX W. LEINBAGH.
